Looking for a reliable guide to sermorelin acetate? Well, you’re not alone. Many researchers are curious about this powerful research peptide and are looking for a detailed overview of its uses, potential benefits and side effects.

This A-Z guide will give you a complete overview of sermorelin including what it’s used for, how it differs from “regular” sermorelin (hint: it doesn’t!), and the most common side effects it causes. In addition, we’ll provide some information and resources that will help you find and buy sermorelin acetate online at the best prices.

What is Sermorelin Acetate?

Sermorelin is an analogue of human growth hormone-releasing hormone (GHRH) whereas “acetate” simply refers to the acetate salt form of regular sermorelin. It contains the first 29 amino acids of GHRH, making it the shortest synthetic peptide to have the full biological activity of GHRH [1]. Sermorelin can be administered intravenously or subcutaneously to stimulate human growth hormone (HGH) secretion from the anterior pituitary.

So what exactly is HGH and why is it important?

Human Growth Hormone (HGH) is produced naturally by the body and serves to regulate a wide variety of bodily functions. It participates in the endocrine system and acts as a chemical signal to your body for regulating a number of processes. These include:

  • Longitudinal growth [2],
  • Sleep,
  • Reproduction,
  • Immune function,
  • Physical performance [3],
  • Bodily composition [4],
  • Mental well-being, and
  • The aging process.

Sermorelin acetate helps increase HGH production and secretion, which can enhance and improve the above processes, especially in patients with HGH deficiency. This peptide can also be used to supplement the body’s natural levels of HGH in elderly subjects as these levels decline with age [4].

Is Sermorelin Acetate Different From “Regular” Sermorelin?

Sermorelin acetate and “regular” sermorelin are essentially the same thing.

The names are used interchangeably and there is no discernible difference between sermorelin acetate and sermorelin. Other names for this compound include sermorelin peptide, GHRH (1-29), Geref and Gerel. Each of these names refer to the peptides that contain the first 29 amino acids of GHRH.

When you’re searching for information about sermorelin acetate online, you’ll find that the term sermorelin is more commonly used over sermorelin acetate or any of the other names.

Benefits of Sermorelin Acetate

Numerous sermorelin benefits have been reported both in scientific literature and anecdotally. Here’s a review of the main research-backed benefits offered by sermorelin.

Diagnosis of growth hormone deficiency in children

Sermorelin’s main clinical use is to diagnose and treat children with idiopathic growth hormone deficiency [1]. When administered intravenously at a dose of 1μg/kg body weight, sermorelin produces a rapid hormone response, making it more efficient at diagnosing this condition compared with other provocative tests.

Treatment of men with hypogonadism

Sermorelin is used to help manage the body composition of men with metabolic syndrome or subclinical hypogonadism (SH) [5]. It has been shown to be safe and well tolerated when used for this purpose.

Better safety profile than HGH

Sermorelin encourages the production of natural HGH in the body and has the full biological properties of GHRH, yet has a much better safety profile than other forms of HGH such as somatropin. Doctors are more likely to prescribe sermorelin as an HGH alternative because the latter has a much more concerning safety profile.

Increases HGH production and secretion

Sermorelin increases the production and release of HGH in the body. In a study on rainbow trout, sermorelin acetate was shown to be effective at stimulating the pituitary gland to naturally produce and deliver more HGH into the system [6].

Increases lean body mass and decreases fat

A study conducted on swine showed that sermorelin can enhance the body’s ability to build and repair tissue faster [7]. The results of a human study into the effects of HGH in men over 60 years old showed that the subcutaneous administration of recombinant biosynthetic HGH can increase lean body mass and decrease fat. Researchers found that “lean body mass and the average density of the lumbar vertebrae increased by 8.8 percent and 1.6 percent respectively, and adipose-tissue mass decreased by 14.4 percent” over a 12-month period [4].

Enhances athletic performance

Anecdotal reports indicate that sermorelin acetate is popular among athletes and bodybuilders due to its purported ability to enhance athletic performance. In a study funded primarily by the World Anti-Doping Agency (WADA), growth hormone supplementation was found to have a significant influence on “body composition and increased sprint capacity when administered alone and in combination with testosterone” [8].

Improves skin

There’s a proven link between diminished secretion of growth hormone and the thinning of the skin that occurs in old age [4]. One study found that growth hormone is able to “stimulate the collagen synthesis in human tendon and skeletal muscle”, suggesting that GH supplementation may help improve skin complexion, flexibility and thickness [9].

The above claims suggest that sermorelin offers many benefits and makes an interesting candidate for further research.

Sermorelin Side Effects | What You MUST Know

Overall, sermorelin usage has not been associated with any major side effects such as cancer or diabetes and scientific literature suggests that it is generally well tolerated. While the recommended dosages of sermorelin have not been directly compared with those of somatropin, the majority of peer-reviewed studies have reported minimal to no side effects.

Some of the minor sermorelin side effects and adverse events that have been most commonly reported are [10,11]:

  • Nausea,
  • Vomiting,
  • Headaches,
  • Flushing or redness in the face [1],
  • Loss of color in the face or paleness,
  • Swelling, achiness, redness, or discomfort at the injection site [1],
  • Funny taste in the mouth.

Occasionally, sermorelin subjects do report some more serious side effects, although these are much less common. Reported sermorelin side effects include [10]:

  • Rash
  • Hives
  • Itching
  • Difficulty breathing/shortness of breath
  • Tightness in chest
  • Inflammation/swelling of mouth, tongue, lips, or other facial features

Researchers should note that allergic reactions are possible (although, again, uncommon). Any subject experiencing any of the above more severe side effects should seek immediate medical attention.

It is recommended that sermorelin be administered on an empty stomach right before bed in order to maximize its benefits. Nighttime is when the natural GH levels in the body are at their peak.

It’s also important to note that higher sermorelin dosage increases the risk of experiencing these side effects. Therefore, it is recommended that subjects begin with the lowest possible dose for a cycle to see how the body responds. The subject can incrementally up the dosage with each cycle and monitor the effects it has on the body and tolerance levels.
Adjusting the dosage of sermorelin mid-cycle can increase the chances of the subject experiencing negative side effects. It’s important to finish out one cycle before considering changing the dose, and keeping the schedule and dosage consistent. This will help the body maintain consistent sermorelin and GH levels, reducing the chances of side effects.
